The word "so" is a conjunction or adverb, you don't begin sentences with it. This is another goofy language fad.
Don't you love news people who tell a news story and improperly use "literally" all the time?
"He literally ran from the fire at 100mph."
Now, why do some guys feel the need to waste words and add to radio congestion by adding "...checking in with you...". When the controller hears you say "Skyblue 245 at flight level 370" he kinda automatically knows that you are checking in and that you are "with him". Just sloppy and unnecessary but I guess some guys like hearing their own voice.
